This blockchain-themed maths puzzle can earn you a share of $100,000

There’s a (supposed) problem with blockchain: it’s too resource-intensive, so Amazon Web Services (AWS) has backed a $100,000 maths competition to “forever change” the technology. Given 1024-bit input x, compute the verifiable delay function ‘h=x^(2^t) mod N’ as fast as possible. t=2^30 N=124066695684124741398798927404814432744698427125735684128131855064976895337309138910015071214657674309443149407457493434579063840841220334555160125016331040933690674569571217337630239191517205721310197608387239846364360850220896772964978569683229449266819903414117058030106528073928633017118689826625594484331 If it helps, the puzzle above relates specifically to Verifiable Delay Functions…
